Abstract

The invention discloses a double-injection device for an improved-type injection mold. The double-injection device for the improved-type injection mold comprises first clamping plates, second clamping plates, an injection rod and hooks; first baffle blocks are respectively arranged at two sides of the first clamping plates; second baffle blocks are respectively arranged at two sides of the second clamping plates; the hooks are hanged and hooked on the first baffle blocks through slide support plates; and the ejection rod is simultaneously connected between the first clamping plates and the second clamping plates in series. Through using the mode, according to the double-injection device, the production cost can be lowered; the quality is stable; and the production efficiency is high.

Description

A kind of secondary ejection device of modified form injection mold
Technical field
The present invention relates to the plastic mould technical field, particularly relate to a kind of secondary ejection device of modified form injection mold.
Background technology
At present, in the face of global stagflation, the cry that the client reduces product price constantly strengthens, and raw material and human cost constantly increase, and makes in production process at plastic cement products, and the perfection of pursuing each link realizes, to realize that the high-quality of whole process is with efficient.And in plastic mould, old ejection system in use, is installed and need the pincers worker master worker carefully be installed, and even all requires pincers worker to participate in installing when mould maintains, and has greatly increased the difficulty of work; When injection moulding was produced, the frequent inefficacy due to mechanism caused the product sticking to mould, 16 caves often become 13 caves, 12 caves even still less, product quality, machine mobility and production efficiency are adversely effected, it is undesired to produce, repair rate is high, and labour intensity is large, the material knotty problem such as be wasted.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of secondary ejection device of modified form injection mold, has reduced production cost, steady quality, and production efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the secondary ejection device that a kind of modified form injection mold is provided, comprise: the first clamping plate, the second clamping plate, push rod and hook, described the first clamping plate both sides arrange respectively the first block, the both sides of described the second clamping plate are respectively arranged with the second block, described hook buckles on the first block by sliding support plate, and described push rod is serially connected in the centre of the first clamping plate and the second clamping plate simultaneously.
In a preferred embodiment of the present invention, for considering that the broken needle phenomenon appears when the pusher in push rod because stroke is long, push rod is divided into two parts, described push rod comprises the first push rod and the second push rod, the diameter of described the first push rod is less than the diameter of the second push rod, and described the first push rod and the second push rod are arranged on same axis.
In a preferred embodiment of the present invention, described the first block is fixed by screws in the both sides of the first clamping plate; Described the second block is fixed by screws in the both sides of the second clamping plate.
The invention has the beneficial effects as follows: the mode that the secondary ejection device of modified form injection mold of the present invention adopts the outer hook of mold clamp board and clamping plate to coordinate with block, reduced the mould inside ejecting structure, sticking to mould not, repair rate is low, increase the distribution of product quantity in die cavity, product quality, machine mobility and production efficiency all increase.
Description of drawings
Fig. 1 is the mold closing structural representation of the secondary ejection device of modified form injection mold of the present invention;
Fig. 2 is the schematic diagram of material ejecting structure for the first time of the secondary ejection device of modified form injection mold of the present invention;
Fig. 3 is the schematic diagram of material ejecting structure for the second time of the secondary ejection device of modified form injection mold of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, the first clamping plate; 2, the second clamping plate; 3, push rod; 4, hook; 10, the first block; 20, the second block; 30, the first push rod; 31, the second push rod.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also Fig. 1, Fig. 2 and Fig. 3, the embodiment of the present invention comprises: a kind of secondary ejection device of modified form injection mold, comprise: the first clamping plate 1, the second clamping plate 2, push rod 3 and link up with 4, the first clamping plate 1 both sides arrange respectively the first block 10, the both sides of the second clamping plate 2 are respectively arranged with the second block 20, hook 4 buckles on the first block 10 by sliding support plate 5, and push rod 3 is serially connected in the centre of the first clamping plate 1 and the second clamping plate 2 simultaneously.
Furtherly, described push rod 3 comprises the diameter of the first push rod 30 and the second push rod 31, the first push rods 30 greater than the diameter of the second push rod 31, and the first push rod 30 and the second push rod 31 are arranged on same axis; The first block 10 is fixed by screws in the both sides of the first clamping plate 1; The second block 20 is fixed by screws in the both sides of the second clamping plate 2.
the course of work of the secondary ejection device of modified form injection mold of the present invention is: under the mold closing state, hook 4 is held on the first block 10, after injection moulding is completed, hook 4 breaks away from the first block 10, promoting first clamping plate 1 drive the first push rod 30 moves forward, the first push rod 30 promotes again the second push rod 31 and moves forward, at this moment product only detaches a part in cavity body of mould, the first clamping plate 1 stop motion, again promoting separately the second clamping plate 31 moves forward, at this moment between the first clamping plate 1 and the second clamping plate 2, certain gap has been arranged, the first push rod 30 also stops mobile, only have the second push rod 31 again to promote the interior product 5 of cavity body of mould, and product 5 is broken away from die cavity, complete and take off material.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
